VACUUM GASOLENE FEED-TAN K.

To all whom it may concern:

Be it known that I JAMES SHEPHARD, citi- I zen of the United tates, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Vacuum Gasolene F eed-Tanks, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanyingfdrawings, which for-ma part of this specification.

My invention relates to a vacuum gasolene feed tank, for motor driven cars, shown in the accompanying drawings and more particularly described in the following specification and claims.

One object of the present invention is an improvement in the general construction of tanks of this character, the same being relatively more simple in construction, less expensiveto manufacture, and more efficient in its operation.

WVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed without departing from the spirit of the same.

In the accompanying drawings forming part of this specification Figure 1 is a diagrammatic view showing a motor vehicle, an internal combustion engine, the intake manifold of the engine, carasolene fuel tank, the vacuum feed tank, and the respective connections between the several parts.

Fig. 2 is a plan view of the vacuum feed tank attached to the dash or body of the vehicle. a I

Fig. 3 is a vertical cross-sectional view on line 33 of Fig. 2. I

Fig. 4 is a fragmentary cross-sectional view on line 44 of Fig. 2, through the valves controlling the suction and air-vent pipes.

Fig. 5 is a vertical cross-sectional. view through the tank with the float raised as when closing the suctiOncut-Olf valve and opening the air-vent valve that the fuel may pass to the lower tank through the discharge Specification of Letters Patent.

valve Which is opened when the float reaches a redetermined altitude.

1g. dis a side elevation of the float and cooperating parts, with the float in its lowermost position, as when the upper tank is fillin Fig. 7 is a side elevation of the float and cooperating parts, with the float in its ele vated position as shown in Fig. 5.

F1g. 8 is an elevation of the float andcooperating elements viewed at right angles to Flg. 6, showing the discharge valve in section.

Referring now to the letters of reference placed upon the drawings A denotes an internal combustion engine, B, its intake manifold, C, acarbureter connected with the manifold. D, is a gasolene supply tank and E, indicates the dash of a motor vehicle. v

F and F denote a pair of super-imposed tanks secured to the dash or other support I by clips f, bolted thereto.

1s a plpe connection leading from the intake manifold B to a fitting having a port opening into the upper tank F, controlled by a valve H. I, indicates an air-vent for the upper tank controlled by a ball valve 1, which is in turn raised from its seat by the thrust of anupstandin'g pin I sup orted by a cross arm J, on which the valve l is also mounted.

K, is a guide rod having a limited vertical movement to which the cross arm J is secured.

L, is a float sleeved upon the guide rod K, which is adapted to raise the uide rod upon the gasolene attaining a su cient altitude in the tank, due to the float contacting with the stop or abutment M, which is in turn secured to the guide rod. The lower end of let orifice of the valve body ;the pinbeing secured to a cross-bar N secured to a vertical guide rod N extending through the valve body N and engaged to the projecting arm N, which is in turn soldered or pinned to the guide rod K. a

P, is a weighted lever pivoted at P to a supply tank, a check valve for said last named a pipe, a valve casing, a passage between the valve casing and the lower tank, a valve in said valve casing for controlling the delivery of fuel between the upper and lower chambers, a float housed in the upper chamber, and means simultaneously actuated by the float adapted to close and to maintain in a closed position the valve in the suction pipe, to open and to maintain in an open position the valve for controlling the admission of air to the upper chamber, and also to open and to maintain in an open position the valve controlling the delivery of fuel from the upper to the lower chamber upon the float attaining a predetermined high level in the upper tank, said means being adapted to be actuated by said float to release said valves that they may function in their normal positions upon the float descending through the discharge of V the fuel to a predetermined low level.

3. In a device of the character described, a gasolene tank comprising an upper and a lower chamber, a suction pipe adapted to connect the upper chamber withthe intake manifold of an engine, a valve for controlling the suction pipe, an air relief valve for the upper chamber, a fuel pipe for connecting the upper chamber with a fuel supply tank, a check valve for said fuel pipe, a passage between the upper and lower chambers, a valve confined within said passage for cOntrolling the delivery of fuel from the upper to the lower tank, a rod having a limited vertical movement, plural means respectively connecting said rod with the valve for controlling the suction pipe, the air relief valve, and the valve controlling the delivery of fuel from the upper to the lower tank; a float adapted to lift said rod, whereby the several valves may be simultaneously operated, means adapted to support the rod when raised by said float and to release said rod when tripped by the float upon its return to trolling said pipe, an air relief valve for the upper chamber, means for delivering liquid fuel to the upper chamber, a passage for delivering the liquid fuel from the upper to the lower chamber, a valve controlling the delivery of the liquid fuel from the upper to the lower chamber, a rod having a limited vertical movement with which said valves are respectively connected for simultaneous operation, a float adapted to raise said rod, and a weighted lever adapted to support said rod when raised and to be tripped by the float upon the descent ,of the latter, whereby'the valves may function in their respective adjusted positions.

5. In a device of the character described, a gasolene tank comprising an upper and a lower chamber, a valved suction pipe connected with the upper chamber, an air relief valve for the upper chamber, means for de livering liquid fuel to the upper chamber, a passage for delivering the liquid fuel from the upper chamber to the lower chamber, a

valve controlling the delivery of the liquid fuel from the upper chamber to the lower a chamber, a rod having vertical movement with which all of said valves are respectively connected for simultaneous operation, a float adapted to raise said rod, and means including a lever adapted to support said rod when the latter is raised and disposed in the path of the float to be tripped by the latter upon descent of the float, whereby the valves may function in their respective posi tions.

In testimony whereof, I sign this specification in the presence of two witnesses:
